Thanks for that, Jim. Pretty much what I expected, with the (for many
counter-intuitive) result that the high capacitance cable had the
flattest response - the expected result of having a better
characteristic impedance match.

You could also say that it is the low inductance cable that has the
flattest response.
That's not at all counter-intuitive.

Interesting. I just selected a low inductance cable for a certain job over
one where some attempt had been made to make it 'an impedance' by having
the cores kept further apart.
